b.Introduction: b.During the 19th and 20th centuries, the Wars were the cause of many amputations among military and civilians. Despite the absence of armed conflict in our country, we notice a high frequency of major amputations in our activity. b.Objective: b.The aim of this work was to study the causes of major amputations observed in our practice in order to develop preventive measures. b.Materials and Methodb.b.: b.This was a descriptive retrospective study over a 6-year period, from January 1, 2008 to December 31, 2014. The following parameters were studied: epidemiological aspects (age according to WHO age groups and gender of patients), type of amputation, level of amputation and causes. b.Resultsb.b.: b.Two hundred and fifty-two patients were included. The distribution of amputations by cause and age group showed two distinct entities: The forms of the young subject where there was a predominance of tumour and traumatic causes;and the forms of the elderly person caused by vascular infections and conditions. Infections were the main cause of amputation in both sexes. b.Conclusionb.b.: b.The causes of major limb amputations vary according to age and limb: tumor and trauma in young people and for the upper limb, infectious and vascular in the elderly and for the lower limb.

The upgrade of the mAX-lab.inj.c.or and the c.nstruc.ion of mAX Ⅲ, provided the opportunity for upgrading the tagged-photon fac.lity and thus lead to the possib.lity of more extensive program in nuc.ear physic. researc.. This upgrade inc.eased the inj.c.ed elec.ron energy to an eventual maximum of 250 meV and allows for the extrac.ion of elec.rons from the mAX Ⅰ ring operated in the stretc.er mode. The first stretc.ed b.am was delivered in Septemb.r 2005. The tagged-photon fac.lity was c.mmissioned in parallel with the c.mmissioning of new experimental equipment. The PAc.approved experimental program is c.rrent in progress, inc.uding measurements of pion photoproduc.ion b.low the △（1232）. The efforts at the tagged photon-fac.lity are pursued within an international c.llab.ration with around fifty memb.rs.

This paper presents the results of the applic.tion of a c.ld spray tec.nique for struc.uring metallic.surfac.s with mic.opartic.es. The resulting c.anges in surfac. properties were c.arac.erized to ob.erve their influenc.s on the trib.logic.l b.havior of the struc.ured surfac.. The spray tec.nique was applied to a tec.nic.l c.mponent, a 16mnc.5 steel c.ain pin, designed to b. mounted in a linear rec.proc.ting trib.meter. TiO2 mic.opartic.es were used to struc.ure the surfac. with a homogeneous distrib.tion of singly dispersed partic.es, rather than a homogeneous c.osed c.ating on the surfac.. Trib.meter tests were performed to direc.ly c.mpare struc.ured and unstruc.ured c.ain pins, and a signific.ntly reduc.d sliding fric.ion c.effic.ent was ob.erved for the struc.ured pin. The pins were c.arac.erized in detail b. surfac. analysis prior to and after applic.tion of the trib.logic.l load to set the surfac. parameters and surfac. c.emistry, even on the mic.osc.le. It was c.nfirmed that the partic.e struc.uring induc.d c.anges in the surfac. properties, and the durab.lity of the c.anges after trib.logic.l loading was evaluated.

b.c.ground It is well known that b.th pre-exc.sing and gestational diab.tes mellitus in pregnanc. is assoc.ated with multiple maternal and fetal c.mplic.tions. There are various guidelines developed to reduc. these c.mplic.tions, yet there is no universal agreement regarding the ideal management. For those with pre-exc.ting or gestational diab.tes mellitus, the c.ntrol of b.ood sugar is assessed either with 1st-hour post-prandial b.ood sugar values or with the 2nd-hour post-prandial b.ood sugar values. Ob.12}c.ive To c.mpare the long-term b.ood gluc.se c.ntrol (Hb.1c.values) of pregnant women b. utilizing results of 1-hour postprandial b.ood sugar values against 2-hour post-prandial b.ood sugar values, in the antenatal ward at the professorial unit, Teac.ing hospital Peradeniya. materials and methods A prospec.ive c.hort study was c.rried out among 138 pregnant women with diab.tes mellitus, who were managed in two different c.inic. at the professorial unit, Teac.ing hospital Peradeniya. The b.ood gluc.se c.ntrol in group 1 (n = 69) was assessed and optimized with 1st-hour postprandial b.ood sugar values and group 2 (n = 69) was evaluated with 2nd-hour postprandial values throughout the pregnanc.es. Following delivery, all sub.12}c.s were reassessed with b.ood Hb.1c.and analyzed with the independent t-test. Feto-maternal c.mplic.tions were analyzed and evaluated using desc.iptive statistic. and c.i-Square tests. Results Of the sub.12}c.s, 97.1% were diagnosed with gestational diab.tes mellitus. The mean value of Hb.1c.for group 1, managed with 1st-hour b.ood gluc.se values was 5.73 and 6.04 (p = 0.02) respec.ively for group 2. Fetal mac.osomia was also signific.ntly (p b.ood sugar c.ntrol group. c.nc.usion Long-term c.ntrol of b.ood sugar was signific.ntly superior among the sub.12}c.s managed with 1st-hour postprandial b.ood sugars with a statistic.lly signific.nt

A study was c.nduc.ed to estab.ish the prevalenc. and severity of Tomato leaf c.rl viral disease in the maj.r agroc.imatic.tomato c.ltivating regions of Guj.rat. Distric.s of Gandhinagar, Kheda, mehsana, Panc.mahal and Raj.ot of Guj.rat were surveyed. The survey aimed at assessing types of symptoms, severity and yield loss in the tomato plants. Results ob.ained indic.te vast spread of Tomato leaf c.rl virus in maj.rity of the tomato fields in Guj.rat. The maximum infec.ion was ob.erved in the Kheda distric. with almost c.mplete c.op loss followed b. mehasna and Gandhinagar distric.s showing high prevalenc. of infec.ion. Influenc. of the c.imatic.c.nditions and c.ltural prac.ic.s were ob.erved on the level of infec.ion.

The wall shear stress （WSS） that a moving fluid exerts on a surfac. affec.s many proc.sses inc.uding those relating to vasc.lar func.ion. WSS plays an important role in normal physiology （e.g. angiogenesis） and affec.s the mic.ovasc.lature＇s primary func.ion of molec.lar transport. Points of fluc.uating WSS show ab.ormalities in a numb.r of diseases; however, there is no estab.ished tec.nique for measuring WSS direc.ly in physiologic.l systems. All c.rrent methods rely on estimates ob.ained from measured veloc.ty gradients in b.lk flow data. In this work, we report a nanosensor that c.n direc.ly measure WSS in mic.ofluidic.c.amb.rs with sub.mic.on spatial resolution b. using a spec.fic.type of virus, the b.c.eriophage m13, whic. has b.en fluoresc.ntly lab.led and anc.ored to a surfac.. It is demonstrated that the nanosensor c.n b. c.lib.ated and adapted for b.ologic.l tissue, revealing WSS in mic.o-domains of c.lls that c.nnot b. c.lc.lated ac.urately from b.lk flow measurements. This method lends itself to a platform applic.b.e to many applic.tions in b.ology and mic.ofluidic..
